The postharvest changes of `Saba' banana fruits from plants in well-drained and waterlogged areas were characterized and compared to determine the difference in behaviour and quality, and whether the difference could be associated with stress response. Fruits from waterlogged plants exhibited accelerated ripening. This was accompanied by increases in levels of 1-aminocyclopropane-1-carboxylic acid (ACC) and ethylene which control the onset of various physico-chemical changes associated with ripening: color development, decrease in peel and pulp firmness, hydrolysis of starch, accumulation of sugars and decline in alcohol-insoluble solids (AIS) content. Green-and shelf-life were also reduced compared to fruits from plants in the well-drained area. Stress-related changes such as earlier onset of ethylene and ACC increases, which accelerate ripening, could be attributed to stress experienced by the plant during growth and development. These changes might be useful as indicators of potential quality problems that require thorough planning before the production period
